To @ZZ wiz/0m z't-mwy concern..-

Be it known that I, JAMES W. PATERSON, a citizen of the United States, residing at Ghicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Shade-Fixtures, of which the following is a specification.

This invention relates to an improvement in shade-fixtures of that class adapted to be securedv at the lower margin of a curtainshade or the like and having at the opposite ends thereof parts adapted to engage the jamb of the window in which said shade is secured. Heretofore devices have been prodevice of the clas's described constructed in such manner thatV the same at all times holds the lower margin o f the shade in a horizontal position.

The invention consists in the matters hereinafter described, and more fully pointed out and defined in the appended claims.

In the drawings, Figure 1 is a front elevation of a window and shade provided with a device embodying my invention. Fig. 2 is a longitudinal vertical section of one end of the shade-fixture. Fig. 3 is an end elevation of the same.

As shown in the drawings, in which my invention is shown as applied to a car-window, A indicates a curtain-shade. A indicates a tubular'rod Secured to the lower horizontal margin of said shade in any desired manner and having the ends' thereof projecting, as shown, slightlybeyond the side margins of the same.

B indicates the window-sash. C indicates the frame therefor, the jambs thereof having in the vertical sides thereof adjacent to said sash vertical grooves, as shown in Fig. l, adapted to receive therein the heads A3 A3,

rigidly secured at opposite ends of said tubular rod. Said vertical grooves may be pro- Vvided'in the jamb itself or vertical stops c may be secured on the inner face of each jamb, providing between the same a groove adapted to receive said heads. A2 A2 indicate milled nuts, each provided with an axial aperture and adapted to engage, respectively, the opposite ends of said tubular rod and provide a connection between the Same andvsaid heads A3 A3. Said heads, as shown, are each provided on each side thereof with oppositelyextending arms a3 a3, directed at right angles with the tubular rod A. Said arms are provided at their outer ends with rollers a3, adapted to track on said jambs within said grooves and designed to permit vertical movement of said device as a whole.

D D indicate longitudinally-movable rods or plungers yieldingly secured, respectively, each in one end of Said tubular rod A and having the outer ends thereof each provided with a friction-foot D', adapted to be pressed yieldingly against the jamb of the window in said groove and acting to resist vertical Inovement of said rod.

Referring now more particularly to features of construction, the said curtain or shade A will usually be provided at its top with a spring-roller of any desired construction orother means permitting vertical movement of the curtain in said frame. The said rod A is secu red to the lower horizontal Inargin of said shade in any desired manner and may be either tubular throughout itsl entire extent or may be provided with tubular ends, said ends, as Shown, being provided with internal screw-threads and projecting slightly beyond the lateral margin of the curtain. The milled nut A2 has at one end thereof screw-threads complemental to the screwthreads in the end of the rod A', and at its other end is of reduced diameter and, as shown, is provided with a peripheral groove; The milled portion of said nut A3'is'located centrally thereof and, as shown, is of the same diameter as the rod A'andform's when screwed into the end thereof essentially a continuation of the same. The heads A3 A3 may be constructed of casting,.of brass or other Suitable metal, or may be formed of sheet or stamped metal, as preferred. The

IOO

same are secured upon the ends of the rod Al by means ot' the said milled nuts, the reduced grooved ends of which are secured each in a socket located centrally of said head by means of a set-screw engaging the walls of said head and having its inner end within said groove of said nut. Said heads on the outer side thereof or that adjacent to the jamb are straight, and the arms a2 (t2 thereof are in alinement and adapted to have sliding movement within said groove. The rollers a3 a3, secured at the outer ends ot' said arms, project beyond the vertical face thereof into position to engage the jamb, and thereby provide an antifrict ion device adapted to permit like movement at each end of said rod independent of the point of application of force.

Within each tubular end of the rod A is secured the tail-block d. The same is provided wih an axial aperture and may be se cured in place by any desired means, that herein shown being a set-screw d', acting to force said tail-block into engagement. with the inner surface of the tubular rod A'. Said nuts A2 and heads A3 are also provided with axial apertures, and a socket or recess is formed in the vertical face of each head, adapted to secure within the same the friction-foot- D". Said friction-feet, as shown, consist each of a block or clip of metal adapt.- eJ to lie within said recess in a head A3, longitudinally thereof, and are each provided on their outer side with a pad of resilient material, such as leather or the like. The same are provided centrally on the inner side with a socket.- adapted to receive and afford attachment for the outer end of the plunger D. Said plungers are located one in each end of said rod A, with the inner end thereof lying in the aperture of said tail-block and with the outer end of the same extending outwardlythrough the apertures in said nut and head and rigidly secured to the friction-foot.,

as before described. The said plunger near its middle part is provided with a stop d3, rigidly secured thereto, and a pushing-spring, herein shown as a spiral spring,'surrounds said rod. One end thereof engages the said stop and the other of which engages the tailblock d, thereby acting to hold the outer end of said rod, with the friction-foot thereon, in its extended position. For the purpose of providing greater amplitude of movement for the said rod the milled nut A2 may be provided at its inner end with a socket or recess adapted to receive the stop d3 and the end of the spring d4; but obviously the same is not essential to the successful operation of this invention.

Obviously if a rod having a solid central part and provided with tubular ends be used the tail-block d may be omitted.

The operation of my device is as follows: The tubular rod A being secured on the lower margin of the curtain or shade, as indicated in Fig. l, and the parts assembled, as indicated in Fig. 2, the device is adjusted to the window-frame by turning the milled nut A2 inwardlyor outwardly. inasmuch as the device is symmetrical, or, in other words, is provided with like ends, a large adjusting-space is not necessary. Onel end ofthe device having been inserted in the groove on the front face of the windowjamb, theleugth of the device may be modified by means of rotation of said milled nuts at each end thereof to permit the insertion of the opposite end in the corresponding `groove. The rod may be lengthened suiiiciently by the reverse rotation of one or both of said nuts to bring the wheels or rollers at each end of the deviceinto bearing contact against the jamb. Obviously when all four of said rollers are in bearing contact the curtain-rod must necessarily be in a horizontal position. 'Ihe friction foot D', forced outwardly bythe action of its springs into contact with the respective jam bs adjacent thereto, acts to hold the shade from upward or downward movement. Obviously the said springs may be adjusted to any desired degree of tension, thereby permitting said friction-feet to be held lightly against said jambs or to be pressed against the same with considerable force, as may be desired. It is also obvious from the construction described that the said heads, while adjustable longitudinally of the rod, are when once adjusted held rigidly with respect thereto and that in consequence downward movementat one end of said curtain-rod will of necessity produce a like vertical movement at the other end thereof, or, in other words, the rigidity ofthe connection of the head and the rod and the antifriction-bearings at the extremity of each arm of each head operates to produce corresponding movement in each end.

I claim as my inventionl. In a shade-fixture a rod adapted to be secured to the lower margin of a shade and provided at each end with a head having arms oppositely extended at right angles with said rod, means for adjusting said heads longitudinally of said rod and rigidly securing the same relatively to said rod in their adjusted positions, and antifriction devices at the eX- tremity of each arm adapted at all times to engage the window-jamb whereby said rod is at all times held in a horizontal position.
